Check whether the touchpad drivers are installed correctly and if necessary update them. Depending on the kind (and age) of your touchpad you might not be able to do a two-finger scroll but scrolling by using the edge of the touchpad should be possible.

Further to Ke Gu - it is probably only the edges of the pad used for scrolling. This from the AH531 user manual:

Scrolling Up/Down:
To scroll up or down, place your finger on the right side of the pad and move it forward or backward to
scroll up or down.
Scrolling Right/Left:
To scroll right or left, place your finger on the bottom of the pad and move it right or left to scroll right or
left.

It took me a while to work it out for my Sony! There are also other gestures described for continuous scrolling.
